Description

Technical Field

[0001] The present invention relates to the field of USB device management, and in particular to a method, apparatus, device and storage medium for USB device management within a cluster. Background Art

[0002] With the increasing adoption of virtualization technology, virtual machines (VMs) are gradually replacing physical machines in various fields. As the number of VMs grows, so too are the demands placed on them. These demands include improving VM configuration and performance, as well as enabling the use of USB devices in VMs. This greatly improves convenience in many areas. For example, to copy files from a USB drive to a VM, a user needs to plug the USB drive into a USB port on the VM's host and then mount the USB drive to the VM. This allows the VM to read and write files from the USB drive. However, as OpenStack clusters grow and the number of hosts and VMs increases, VMs are distributed across multiple hosts. Mounting USB devices using traditional USB passthrough solutions becomes cumbersome. This requires constantly changing the host where the USB device resides, or preparing a large number of USB devices. Regardless of the type, this approach is cumbersome and inefficient. Furthermore, VMs with mounted USB devices cannot be migrated. Summary of the Invention

[0023] In a second aspect, the present application discloses a USB device management device within a cluster, comprising:

[0024] The device information acquisition module is used to obtain the device information of the locally available USB devices and assign a port number to each of the available USB devices;

[0040] In the prior art, if a user wants to copy files from a USB flash drive to a virtual machine, he needs to insert the USB flash drive into the USB interface of the host where the virtual machine is located, and then mount the USB flash drive to the virtual machine. In this way, the files in the USB flash drive can be read and written in the virtual machine. However, when the openstack cluster becomes larger and the number of hosts and virtual machines increases, the virtual machines will be distributed on different hosts. At this time, it is particularly troublesome to use the traditional USB pass-through solution to mount USB devices, because it is necessary to change the host where the USB device is located or to prepare a large number of USB devices, no matter which type, to use them is relatively cumbersome and inefficient. On the other hand, the virtual machine with the USB device mounted cannot be migrated. In order to overcome the above technical problems, the present application proposes a method for managing USB devices within a cluster, which can solve the problem that USB devices can only be mounted to virtual machines on the host where they are located, and also avoids the limitation that virtual machines cannot be migrated after mounting USB devices.

[0041] The present application embodiment discloses a method for managing USB devices in a cluster, which is applied to hosts in the cluster. Figure 1 As shown, the method may include the following steps:

[0042] Step S11: obtaining device information of locally available USB devices, and assigning a port number to each of the available USB devices.

[0043] In this embodiment, the device information of the locally available USB devices is first obtained, that is, the available USB devices currently connected to the physical host, and a network port number is allocated to each available USB device.

[0044] In this embodiment, obtaining device information of locally available USB devices may include querying a local USB device list and, based on a target parameter field corresponding to each USB device, filtering out virtual USB devices from the USB device list to obtain the device information of the available USB devices. Specifically, upon startup, the computing service of each host in the cluster proactively queries the USB list on the host and filters out unavailable virtual USB devices provided by the operating system to obtain the device information of the available USB devices.

[0045] Step S12: Obtain the host IP, and obtain a unique number corresponding to each available USB device based on the host IP and the port number.

[0046] In this embodiment, by obtaining the host IP, a unique number corresponding to each available USB device is obtained based on the above host IP and port number. In this way, a USB device is uniquely identified by the host IP and network port number, instead of the traditional vendor ID and product ID. This can effectively avoid the disadvantage that when different USB devices have the same vendor ID (manufacturer ID) or product ID (product ID), the cloud platform can only identify one USB device.

[0047] Step S13: sharing the unique numbers corresponding to all available USB devices to the cluster database via the network protocol, so that any host in the cluster can mount the USB device to the target virtual machine according to the unique number of the USB device to be mounted and the ID of the target virtual machine.

[0048] In this embodiment, for example Figure 2As shown, after determining the unique number of the available USB device, a sharing service is started to share the unique number of the USB device via a network protocol. In this embodiment, sharing the unique numbers corresponding to all the available USB devices to the cluster database via the network protocol may include: uploading the unique numbers corresponding to all the available USB devices and associated parameter information to the cluster database via the Transmission Control Protocol; wherein the parameter information includes the host name, the device manufacturer ID, and the device product ID. That is, sharing the unique number corresponding to the USB device and the associated parameter information to the cluster database via the Transmission Control Protocol (TCP), wherein the parameter information includes but is not limited to the host name of the host where the USB device is located, the USB device manufacturer ID (product ID), and the USB device product ID (vendor ID). That is, the data shared to the cluster database may specifically include but is not limited to the unique number consisting of the host IP address and port number, as well as the host name, product ID, and vendor ID. Each host in the cluster can share the available USB devices on its local machine in the above manner, so that when any host in the cluster needs data in a certain USB device, it can mount the USB device to the target virtual machine based on the unique number of the required USB device to be mounted and the ID of the target virtual machine. Specifically, when a user wants to mount a USB device to a virtual machine, they can select the USB device and the target virtual machine to mount it from the USB list in the virtual machine device management interface. This not only solves the problem that USB devices can only be mounted to virtual machines on the host in traditional USB pass-through solutions, but also avoids the limitation that virtual machines cannot migrate after mounting USB devices. It is understandable that in the prior art, after a virtual machine migrates from the current host to another host, it can no longer use the USB devices on the original host, which limits the migration of the virtual machine. This embodiment is suitable for large-scale Openstack cluster scenarios. OpenStack is an open source cloud computing management platform project and a combination of a series of software open source projects.

[0049] In this embodiment, the target virtual machine is a virtual machine created based on Libvirt. The host mounts the USB device to be mounted to the target virtual machine based on the unique number of the USB device to be mounted and the ID of the target virtual machine. This process may include: receiving a mount request; the mount request includes the unique number of the USB device to be mounted and the ID of the target virtual machine; generating redirection configuration information based on the unique number of the USB device to be mounted and the ID of the target virtual machine; and using the Libvirt service to mount the USB device to be mounted to the target virtual machine based on the redirection configuration information. Specifically, the host's computing service will splice the redirdev device's xml file, i.e., the configuration file, based on the virtual machine ID selected by the user and the host IP and port number corresponding to the USB device, and send the request to libvirt. After receiving the request, Libvirt will mount the USB device to be mounted to the target virtual machine.

[0050] In this embodiment, after the unique numbers corresponding to all the available USB devices are shared to the cluster database through the network protocol, it can include: uploading the associated information containing the unique numbers corresponding to all the available USB devices in the cluster database to the cloud management platform; adding corresponding parameter information for each of the USB devices through the cloud management platform; the parameter information includes device usage status and device usage permissions.

[0051] It is understandable that all USB devices in the cluster can be managed through the cloud management platform. By setting usage permissions for USB devices, the security of device sharing can be improved, such as setting which virtual machines can use USB devices. Specifically, the host's API (Application Programming Interface) service can be used to query the database to obtain a list of all available USB devices in the cluster and USB-related information, including a unique number consisting of the host IP and port number, as well as the host name, product ID, vendor ID, etc., and upload them to the cloud platform management interface. The interface will uniformly display the list of available USB devices in the cluster and manage the device usage status and device usage permissions. For example Figure 3 As shown, the administrator logs in to the virtual machine management platform, selects the cloud host in the cloud management platform list, selects Mount USB Device in the cloud host operation list, selects the corresponding host, selects the USB device to be mounted in the host USB list, and sets permissions to implement shared control. As a result, the USB device to be mounted is in a usable state.

[0052] In this embodiment, after mounting the USB device to be mounted to the target virtual machine, the method may further include: updating the device usage status of the USB device to be mounted via the cloud management platform and adding corresponding mounting information; the mounting information includes attribute information of the target virtual machine. Specifically, the status of the USB device to be mounted is set to the usage status, and relevant mounting information is added for the USB device to be mounted. The mounting information includes, but is not limited to, attribute information of the target virtual machine corresponding to the USB device to be mounted, such as the virtual machine ID and memory, thereby displaying information about the virtual machine associated with the USB device.

[0053] In this embodiment, after adding corresponding parameter information for each USB device via the cloud management platform, the method may further include: monitoring the device usage status in real time, and automatically updating the device usage permission based on the type of the device usage status. Specifically, when the device usage status is detected as the aforementioned usage status, the device usage permission of the corresponding device is automatically updated to be unavailable, thereby avoiding anomalies caused by excessive device connections.

[0054] As can be seen from the above, in this embodiment, a port number is assigned to each USB device, and then the host IP and port number are used as a unique number to identify a USB device. Further, based on the above unique number, the USB device on any host in the cluster can be shared through the network protocol. In this way, the virtual machine on any host in the cluster can connect to the required USB device through the host IP and port number, realizing USB device redirection and unified management of all USB devices in the cluster. The use of the virtual machine is no longer limited to using only the USB devices of the host. At the same time, it also avoids the limitation that the virtual machine cannot migrate after mounting the USB device, greatly improving work efficiency.

[0059] As can be seen from the above, in this embodiment, the device information of locally available USB devices is obtained, and a port number is assigned to each of the available USB devices; the host IP is obtained, and the unique number corresponding to each of the available USB devices is obtained based on the host IP and the port number; the unique numbers corresponding to all the available USB devices are shared to the cluster database via the network protocol, so that any host in the cluster can mount the USB device to be mounted to the target virtual machine based on the unique number of the USB device to be mounted and the ID of the target virtual machine. It can be seen that by assigning a port number to each USB device, and then using the host IP and port number as a unique number to identify a USB device, the USB device on any host in the cluster can be shared through the network protocol based on the above unique number. In this way, any virtual machine on any host in the cluster can connect to the required USB device through the host IP and port number, realizing USB device redirection, solving the problem that USB devices can only be mounted to virtual machines on the host in the traditional USB pass-through solution, and also avoiding the limitation that virtual machines cannot migrate after mounting USB devices.
